Abstract
A system and method splices into, or replaces routes identified based on road geometry with routes taken by the same user or other users to create alternate routes that may be selected by a user to display, for example, on a map or for which driving directions can be displayed. Communication of routes traveled by different devices may be received from a server or from another device. A naming convention for road segments and ordered paths of road segments is described.
